I didn't know that she'd been a regular presenter; I stopped watching after that era - but I'm glad she was eventually part of it in a more central way.
She wasn't really a "regular presenter". After the trio left, they basically had a rotating cast of presenters, of which she was one of. But the show got absolutely pummeled by the critics.
Once they got rid of Chris Evans, the show recovered somewhat. With Mat LeBlanc, Flintoff etc. Though not back to the Clarkson stratospheric viewing figures, but I really liked the LeBlanc seasons.
